Progress from Prototype 2 In the morning of my scheduled final laser-cutting, I received news that the machine was down. Thus, I booked another slot the next day and kept in touch with several people for updates regarding the machine. Even though there were some hiccups that happened when I was laser-cutting, I managed to get all the parts ready (after two hours of trial and error with the work-study).
Since I was using a 180 degree servo, only half of the linear mechanism was used. Hence, I had to apply some load onto the bar for it to move downwards and not get stuck at a diagonal angle.
I had also purposely created a smaller whole on the upper disc and a slightly larger hole on the lower disc so the wooden pole would stick to the upper disc better.
Ample of space was given between the disc to slot in a thin wire which was used to hold all six arms together.
The Code The Arduino code was pretty simple as well. Jellica will move at a slow pace by default but when the Ultrasonic Sensor is triggered, it moves faster. Since I wanted the LED lights to be active the whole time, I used two arduinos so the LED does not have to wait for the servos to finishing looping before lighting up.
What is it? The “Uncanny Valley” is a characteristic dip in emotional response that happens when we encounter an entity that is almost, but not quite, human. It was first hypothesised in 1970 by Japanese roboticist Masahiro Mori, who identified that as robots became more human-like, people would find them to be more acceptable and appealing than their mechanical counterparts. But this only held true to up a point. Continue reading [Robotic & Kinetic Media] Thematic Presentation – “The Uncanny Valley”
